MICROFLUIDIC DIAGNOSTIC AND POINT OF CARE DETECTION SYSTEM FOR SARS-COV-2 FROM SALIVA

We present a nucleic acid-based point-of-care diagnostic for the detection of the SARS-CoV-2 from saliva using an additively manufactured microfluidic cartridge. The assay uses reverse transcriptase loop-mediated isothermal amplification (RT-LAMP) to detect the presence of SARS-CoV-2 RNA on-cartridge in a point-of-care optical detection system based on a smartphone. We show positive results within the 10-30 minutes range and integrated biological controls on the cartridge. We demonstrate the microfluidic diagnostic with human patient samples, with results that are consistent with the off-cartridge validation. © 2021 MicroTAS 2021 - 25th International Conference on Miniaturized Systems for Chemistry and Life Sciences.
